Vulvar lipoma: a case report

Abstract

IntroductionVulvar lipoma is a rare tumor localization and only a few cases have been reported. The clinical characteristics of vulvar lipoma are well known. However, it is important to distinguish lipomas from liposarcomas. We report a case of vulvar lipoma and discuss its clinical features, including diagnostic aspects, with emphasis on histopathological evaluation of all excised lesions. We also report and discuss patient management and treatment outcomes.Case presentationWe report the case of a 27-year-old Moroccan woman. Our patient presented with a painless and slow-growing right vulvar mass that had evolved over one year, which had suddenly become uncomfortable when walking. A physical examination revealed a single soft and pasty mass in her left labium majus, which could be mobilized under her skin towards her mons pubis. The largest dimension of the mass measured 6cm. Magnetic resonance imaging showed a homogenous hyperintense mass with a well-defined contour in her left labium majus; a fat-suppressed magnetic resonance image demonstrated a marked signal intensity decrease. The mass was completely removed surgically. A histological examination revealed a circumscribed benign tumor composed of mature adipocytes, confirming the diagnosis of vulvar lipoma.ConclusionVulvar lipomas must be differentiated from liposarcomas, which demonstrate very similar clinical and imaging profiles. The final diagnosis should be based on histopathological evaluation. A precise diagnosis should allow for appropriate surgical treatment.

Spectrum of vulvar lesions: patient’s anxiety, clinician’s concern and pathologist’s diagnostic challenge

“…Imaging modalities like ultrasound or CT are helpful in preoperative diagnosis of these lesions. 23,24 Our study included three cases of VIN III and one case of VIN I. Vulvar Intraepithelial Neoplasia (VIN) is a pathological denomination coined by the International Society for study of vulvo-vaginal diseases (ISSVD) and adopted by the International Society of Gynaecological Pathology (ISGYP) and by the World Health Organization (WHO). It may be asymptomatic or may present with vulvar itching or plaque.…”

Deep-localized lipoma of the vulva

“…Jayi ve ark. [11]. bizim sunduğumuz vakaya benzer şekilde endofitik yerleşimli bir vaka sunmuşlardır ancak bu vakada sunulan vulvar lipomun endofitik yerleşimli olmasına rağmen bizim vakada sunulan vulvar lipom kadar büyük olmadığı görülmüştür.…”

Long-standing vulvar lipoma in a 65-year-old postmenopausal woman

“…Vulvar lipoma is a rare benign mesenchymal tumor. Microscopically, the vulvar lipoma appears as lobules of mature fat cells, separated by fibrous connective tissue bands [1][2][3]. Vulvar lipomas have been identified in different age groups [4], a 27-year-old woman in the Jayi et al [1] case report, 28-and 35-year-olds in the Odoi et al [2] case report, and 65-year-old in this case report.…”

“…Vulvar lipoma is a rare benign mesenchymal tumor, identified in different age groups [1][2][3][4]. The etiology of vulvar lipomas is not clearly identified, while trauma of the vulva is recorded in some cases [5].…”
